is a very easily lead to one of the reasons for failure, most of the customers or the use of hand-soldering method, while the Department of
Large enterprises to adopt high-frequency sub-solder method. These are some places where we should pay attention Oh.
The use of hand-soldering method, Potentiometers time in the welding operation as far as possible in a short period of time, preferably 3 seconds to
To be completed within the maximum contact solder iron temperature less than 270 degrees. If time is too long or too high temperature will cause poor contact and other Potentiometers
Reasons. Be used with caution when soldering flux should avoid the use of water-soluble flux, otherwise, the oxidation of metals and materials encourage mold.
When using high-frequency soldering
potentiometers, attention in the plastic parts: for example, dial knob, plastic push handle, plastic handle, such as when the melting point
Further requirements to achieve high-frequency temperature, if they can not replace the high temperature components.
To avoid additional wiring and when the tin lead solder flow through the circuit board, otherwise easily lead to poor contact
potentiometers.
